John and Jim Harbaugh

Baltimore Sun

Jim Harbaugh (right) had a brief stop in Baltimore during his fine NFL career, splitting time under center with the immortal Eric Zeier in the 1998 season. A decade later, his older brother John -- one year his senior -- was hired as the third coach in Ravens history. They will become the first brothers in NFL history to oppose each other as head coaches when the Ravens host Jim Harbaugh and the 49ers on Thanksgiving Day.
